Young people who are at high risk of type 2 diabetes may want to spend a little more time in the weight room, according to one study. Conducted by University of Southern California researchers, the study was based on a 16-week experiment involving teenagers who were overweight and showed symptoms of insulin resistance. With twice-weekly weight lifting sessions, teens in the study were able to increase their insulin sensitivity by 45%. This dramatic improvement compares with a 1% decline in insulin sensitivity among those study subjects who engaged in no weight training. The findings of this study confirmed past conclusions about the relationship between resistance training and insulin sensitivity.
